PLOT
In a household of three the husband is a salaryman who lives with his younger sister and wife in Tokyo. He is returning home late in the evenings because he plays go, or a Japanese version of chess, with his boss. The wife and sister are unhappy about this. The man's co-worker advises him to stop the late evenings out with the boss, but the man cares less. His sister works at a foreign firm and speaks English. When a man who had earlier visited her workplace returns and asks her out for dinner, she rejects him by lying about a husband. He had made impolite comments about her in English during his earlier visit not realizing she understands him.
